con'cmrnn HINGE.

To all whom it concern.- n

Be it known that I, FRED J. FISHER, a

a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, haveinvented a certain new and useful Improvement in Concealed Hinges, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art 'to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a partof this specification.

This invention relates to concealed hinges and has in view, a concealed hinge provided with a removable pintle-carrier that is so set into the hinge housing that it affords a wide metal post to act as a stop for thehinge arm;

yet the pintle is so positioned in the housing as to allow the use of a long radius arm.

Another feature of the invention is the construction of the hinge arm out of a stamping in the form of a channel stripwhich adds strength to the hinge arm in proportion to its weight.

Still another feature is the use of a rubber bumper on the hinge arm' to engage the abutment so as to lessen the shock of the impact between the hinge arm and theabut ment and do away with the necessity of the usual leather check straps which are used in connection with concealed hinges. The channeled hinge arm makes a very convenient way of carrying this rubber bumper.

Fig. 2 is a similar sectional view taken on a slightly lower plane and showing the door in open position and the hinge parts accordingly. Fig. 3 is a vertical' section showing how the hinge parts are assembled. Fig. dis a cross section of the hinge arm taken on the line provided with a plurality of projections b.

shown in Fig. 1, thereby riveting the plate 0 securely 'to the hinge arm.

The hinge pintle is'held in a pintle-carrier d which comprises a strip of metal bent into a U and having;outwardly-extended portions or what might be termed perpendicular fasten ng lugs by which-the U-like portion, when the -U is tippedon its side and sllpped into the housing as shown in Fig. 3,

may be secured to the housing. 5

The housing comprises a box e open at its front and provided with upward and downward "extensions f by which the box may be secured to the door post and. provided with a pair of sockets g in'the faces of these extensions, in which are adapted to fit the fastenmg lugs on the pintle-carrier.-

The composite housing is constructed in v the following manner A piece of sheet metal is cut into a blank sothat it can be folded to form the plate portions k and h of the extensions f, the one side 11 shown in Figs. 1 and 2, and the top j and bottom is of the box shown in Fig. 3. This would leave the rear and the one side of thebox 30 yet to be covered, and this cover is afforded by soldering a thin metal strip in over the edges of the sidewall, top and bottom of the box. 1A finishing plate} of fairly heavy metal is then spot-welded to the plate portions it. The center of the plate is cut out to coincide with the opening in the front of:

the box, but it will be noted that at theside's In the drawings,Figure-1 is a horizonthe opening in the finishing plate is not as wide as the opening in the box and this opening through the finishing plate, and this is of special importance in the post designated 'mfor this forms a stop for the hinge arm and must needs be strong. Offset at the top and bottom of r the central opening through the finishing plate are a pair of approximately semi-clrcular openings which are cut out of the plate to form in connection with the plate portions 72., which are exposed, sockets 9 already alluded to, which receive the fastening lugs of the pintle-carrier. It will be noted that the plate'portions 71. at these sockets are provided with threaded apertures '11, to receive screws which pass through openings 0 in the lugs of the pintle-carrier. Consequently the pintle-carrier and the hinge arm can be assembled in the composite houslng and disassembled affords the strong'posts. at the side of the therefrom simply by threading the screws into their sockets or taking out the screws.

So the door may be easily disconnected from the door post by simply taking out these two screws that run into the screw sockets n. This arrangement of pintle-carrier and housing is at the present time old, but Ibelieve that the arrangement of the pintle-cairier and housing now to be described is new.

The top j and bottom is of the box are stamped outwardly to form ways 3 which extend from the open side of the boi: rearwardly and obliquely. The sides of these ways converge together. The U-shaped pintle-carrier has complementary and converging edges so that when it is slid into the ways and screwed to the composite housing, these converging walls of the ways and "converging edges of the pintle-carrier wedge together in non-rattling relation. The oblique direction of these ways from front to rear has an important object in makingzpossible the use of a wide post m (see Fig. 1), yet at the same time locating the 'pintle' as. far toward the side of the box as is practical so a large hinge arm will be afforded. The wide hinge post is an important factor for the reason it acts as an abutment to stopthe hinge arm when no straps are used. Inthe construction here described, not only is this hinge post wide but itpresents a widthwise resistance to the striking force 'so as to give great strength.

Within the channeled hinge arm and between the elbow proper and the pintle is set a thick rubber bumper p. The back of this rubber bumper has a V out out of it so that it may be constricted in inserting it in the channeled arm, and after it has been fitted in the arm the portions to the opposite sides of the V channel would'tend to spread, thereby holding the bumper in the channel. From a comparison of Figs. 1 and 2 the action of the bumper will be understood, and it will be seen that it con tacts the wide post m and that by reason of the distortible character of the rubber the impact of one member with the other will be 'deadened. Consequently not only is the very heavy strain ,to the hinge arm and pintle due to metal to metal contact obviated, but also any objectionable noise due to the striking of the metal upon metal.

j The cushioningof the thrust of the hinge arm upon the post is an important thing on account of the very great leverage upon 1 the hinge arm when the width of the door is considered. Heretofore it has been customary to use leather door check straps. These were intended to stop the door just before the arm strikes the abutment or post, but these are objectionable for the reason that they are quite liable' to pull the screws naled by the pintle, an abutment, and a 1 cushioning element secured in the channel of the hinge arm for striking the abutment.

3. A concealed hinge, having in combination, a'housing provided with a way leading from the opening in the housing along one ofthe horizontal walls rearwardly and obliquely to one side and a wide post to act as a stop made possible by the said obliquely disposed way, a pintle-carrier removably securable to said housing and adapted to fit into said way, apintle supported by the carrier, and a hinge arm supported by the pintle. v y

4. A concealed hinge, having in combina- .tion, a housing provided with a finishing plate having a portion forming a comparatively wide post or abutment, the said housing being provided with a box portion having one "or more ways extendingobliquely rearward from the opening at the side of said post, and a pintle-carrier, pintle and hinge arm removably securable in said housing by sliding the pintle-carrier in said obliquely-extending way.

5. In a concealed hinge, the combination of a pintle, means for supporting the same, a hinge arm, an abutment, a cushioning element, and means on the hinge arm for engaging opposite sides of the cushioning element to hold the same in place and in position to strike the abutment.

In testimony whereof, I sign this speci fication.
